Lava Spider
From Tardis Wiki, the free Doctor Who reference
The Lava Spiders were a race from an other dimension. They could input lava into the web to kill their prey quicker then constriction, cooking them alive in the process. After they turned part of Schwarzwald into their web, UNIT sent Dr Elizabeth Klein, Sgt. Pete Wilson and Private Maynard to investigate. They were attacked and imprisoned in the web as food, but were rescued when an incarnation of the Master posing as the Doctor used the Skyheads to blow away the spiders. (AUDIO: Dominion)
